Natural gas and bottled camping gas contain alkanes. Alkanes are hydrocarbons.
State what is meant by a hydrocarbon.
The table shows the names and formulae of the first four alkanes.
| Name | Formula |
|---|---|
| methane | ? |
| ethane | C2H6\mathrm{C_{2}H_{6}}C2H6 |
| ? | C3H8\mathrm{C_{3}H_{8}}C3H8 |
| butane | ? |
Complete the table by giving the missing names and formulae.
Alkanes are described as saturated. State what is meant by saturated.
State the number of covalent bonds formed by each carbon atom in an alkane molecule.
36 exam-style questions on Edexcel GCSE Chemistry 10.2 Hydrocarbons, covering 10.2.1 Formulae and structures of the alkanes, 10.2.2 Alkenes and the C=C functional group, 10.2.3 Addition reactions of alkenes and testing for unsaturation, and 10.2.4 Combustion of alkanes and alkenes. Each one has a worked solution and a mark scheme showing where the marks go.
